The environment around the time of conception can change the VTRNA2-1 gene in a way that lasts for years and may affect disease risk.

Different signals work together to change gene activity and guide hair follicle stem cells to become specific cell types.

TTD hair brittleness is caused by multiple structural abnormalities.

Removing Mediator 1 from certain mouse cells causes teeth to grow hair instead of enamel.

Skin stem cells in hair follicles are important for touch sensation.

Hair follicle stem cells are crucial for touch sensation and proper nerve structure in mice.

Biotin and biotinidase are essential to prevent health issues, and deficiencies require lifelong supplementation.

Adequate vitamin D is crucial for skin health and should be considered in dermatology.

CD8+ T cells are involved in alopecia areata and may cause disease relapse.

Alopecia areata is an incurable autoimmune condition causing hair loss, with research aiming for better treatments.

Genetic variations greatly affect individual metabolism and can impact health and disease risk.

People with Parkinson's disease have higher levels of cortisone in their hair, which may indicate chronic stress hormone dysfunction.

Women with PCOS have more Bifidobacterium in their gut compared to those without PCOS.

Taking triterpenoids from Ganoderma lucidum over a long time can help slow down brain aging and improve overall health in mice.

Female cuckoo color differences are linked to their unique genes and help avoid male harassment.

Women with PCOS are more likely to have skin problems like excessive hair, acne, and hair loss.

Enterococcus faecalis delays wound healing by disrupting cell functions and creating an anti-inflammatory environment.

Pregnant women with PCOS have higher levels of Neurokinin B in the placenta, especially with female babies.

Protein tyrosine kinases are key in male pattern baldness, affecting skin structure, hair growth, and immune responses.

Artemis protein may help control hair growth and health by influencing cell processes.

Adult stem cells with Tp63 can form hair and skin cells when placed in new skin, showing they have hidden abilities for skin repair.

Testosterone makes the connections in the uterus lining simpler and lowers certain protein levels, which might lead to infertility.

Shrunken heads retain some facial features and hair characteristics, allowing for limited individual identification.

Scientists turned rat thymus cells into stem cells that can help repair skin and hair.

FoxN1 gene is essential for proper thymus structure and preventing hair loss.

Flutamide caused damage to male rat reproductive organs and may affect fertility.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

The study suggests computer-assisted analysis of scalp biopsies could improve hair loss diagnosis but needs more validation.

Stem cell niches are crucial for regulating stem cell renewal and differentiation, and understanding them can help in developing regenerative therapies.

Chitosan nanofiber scaffolds improve skin healing and are promising for wound treatment.
